What to Buy Before Your Vasectomy | Dr. Theodore Cisu

The short answer: Before your vasectomy, pick up snug briefs or a jockstrap, a couple of ice packs or bags of frozen peas, over-the-counter pain relief your instructions allow, and loose pants. Then line up a driver if you are taking Valium, a comfortable spot on the couch and something to watch. The semen test comes later.

Why a little prep helps

Recovery from a vasectomy is usually simple. Most men rest for a day or two with ice and snug underwear, and many are back to desk work within a few days. Having what you need at home before you leave means you can go straight to the couch afterward. Your own written instructions come first. This list is a general guide.

What to buy

• Snug briefs or a jockstrap. Supportive underwear keeps things still and is one of the most helpful parts of recovery. Have two or three pairs so you can change. Boxers won't give the same support.
• Ice packs or frozen peas. Two bags let you rotate one while the other refreezes. Peas mold to the area well. Wrap them in a thin cloth and don't put ice directly on skin.
• Over-the-counter pain relief. Buy what your instructions recommend and take it only as directed. If you take blood thinners or have reasons to avoid certain pain relievers, ask at your consultation.
• Loose, comfortable pants. Sweatpants or shorts are easier to wear over supportive underwear and an ice pack.
• Gauze pads, if your instructions say so. A small amount of spotting at the tiny opening can happen. Not everyone needs gauze, so follow what you are told.

What to line up

• A driver, if you take Valium. With Valium, alone or with nitrous oxide, you can't drive yourself home. With nitrous oxide only, it wears off within minutes and you can drive.
• A couch setup. Pillows, a blanket, a towel to set under the ice pack, water and snacks within reach.
• Something to watch or read. Plan a quiet day or two. Many men choose a Friday so they can rest over the weekend. See Friday vasectomy: recover over the weekend.
• Help at home. If you have small kids, arrange for someone else to do the lifting for about a week.
• Time off from the gym. Plan to skip heavy lifting, hard exercise and sex for about a week, or as your instructions say.

What you don't need yet: the semen test

A vasectomy doesn't work right away. About three months and about 30 ejaculations later, a semen test checks that there are no sperm. You have two choices.

• A local lab. Your semen analysis can be done at a lab.
• A mail-in kit from Fellow. If you prefer to test from home, you order a kit directly from Fellow at meetfellow.com, not through Augusta Health, and you pay Fellow's fee.

Either way, keep using other birth control until you are cleared. Learn more in The semen test after a vasectomy.

The night before and the morning of

Follow your pre-procedure instructions about trimming or shaving, showering and eating. Wear or bring your supportive underwear so you can put it on before you leave. If you plan to pay with an HSA or FSA card, bring it. For a day-by-day look at healing, read the Vasectomy recovery timeline.

Frequently asked questions

Do I really need special underwear?

Snug briefs or a jockstrap are strongly recommended. Support keeps swelling down and makes moving around more comfortable.

How long should I ice?

Ice is most helpful during the first day or two. Follow the timing in your instructions, and keep a cloth between the ice and your skin.

What pain reliever should I take?

Use the over-the-counter option your instructions name, at the amount on the label or as directed. Ask at your consultation if you take blood thinners.

Do I need to buy the Fellow kit now?

No. The semen test happens about three months later. You can order a Fellow kit then, or use a local lab instead.

Can I drive myself home?

Yes, if you choose nitrous oxide only. If you take Valium, you need someone to drive you.
